Description

一种资源配置方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种资源配置方法及装置。
背景技术
长期演进及机器类型通信(Long Term Evolution Machine-Type Communication，LTE MTC)是有别于传统LTE通信的技术，LTE MTC不追求数据传输速率、多频段、多天线、全双工传输，而是追求较长的终端装置电池时间，较低廉的终端装置成本，即要求终端能够实现低功耗(Low power consumption)、低成本(Low cost)。
当终端(或UE)没有上行数据或下行数据需要传输时，UE处于无线资源控制(Radio Resource Control，RRC)空闲态(RRC Idle)，当终端有上行数据或下行数据需要传输时，UE处于RRC连接态(RRC Connected)。UE从RRC空闲态转换到RRC连接态需要经过随机接入过程(Random access)，该过程包括四个步骤，
第一步，UE向基站发送随机接入前导码(Preamble)；
第二步，基站向UE发送随机接入响应(Random access response，RAR)消息，其中携带上行定时提前(Timing Advance，TA)和上行资源授权(UL Grant)；
第三步，UE向基站发送消息三(Msg3)，该消息三可以是RRC连接建立请求(RRC Connection Request)消息或RRC连接恢复请求(RRC Connection Resume Request)消息或RRC早传数据请求(RRC Early data Request)消息或RRC连接重建请求(RRC Connection Reestablishment Request)消息；
第四步，基站向UE发送冲突解决(Contention Resolution)消息，即消息四(Msg4)，其中消息四还可以包含对应消息三的RRC连接建立(RRC Connection Setup)消息或RRC连接恢复(RRC Connection Resume)消息或RRC早传数据完成(RRC Early Data Complete)消息或RRC连接重建(RRC Connection Reestablishment)消息或RRC连接释放消息(RRC Connection Release)消息。
在早传数据(Early Data Transmission，EDT)技术引入之前，UE通过RRC连接建立或RRC连接恢复流程来建立/恢复与基站之间的RRC连接，然后在Msg4之后开始传输上下行数据。在EDT技术中，上行数据可以在Msg3中进行传输，下行数据在Msg4中进行传输，在UE只有少量数据需要传输时，可以提高数据传输效率，不需要建立/恢复RRC连接。进一步地，针对MTC和窄带物联网(Narrow Band Internet of Things,NB-IoT)的终端，尤其是一些低移动性或静止的终端(例如，水表，电表，路灯等)，其数据传输不仅具有周期性，而且移动较慢或完全静止。为此，一种在预配置资源上发送上行数据的方法被提出，该预配置资源用于UE在空闲态时进行数据传输，该方法不需要随机接入过程中的第一、二步，可直接进行第三、四步，即直接进行上下行数据的传输。在预配置资源分配给UE之后，如果UE不能进行合理的释放，则会造成预配置资源浪费。
发明内容
本申请提供一种资源配置方法及装置，本申请所提供的方法和装置解决现有技术中预配置资源分配给UE之后，如果UE不能进行合理的释放，则会造成预配置资源浪费的问 题。
第一方面，提供一种资源配置方法，包括：
用户设备UE接收基站发送的第一消息，所述第一消息携带预配置资源的配置信息；其中，所述预配置资源用于所述UE在空闲态时进行数据传输；
所述UE获得第一指示信息，并根据所述第一指示信息确定释放所述预配置资源。
在本实施例中，UE根据配置信息分配预配置资源之后，可以根据第一指示信息确定预配置资源没有得到有效使用需要释放掉，以便预配置资源能够回收再利用。
可选的，在确定是否释放预配置资源的情况至少可以分为两种，一种是UE根据预配置资源的使用情况，确定预配置资源是否有效，如果无效，则释放预配置资源；另外一种是如果基站的负载过大时，基站可以直接发送第一指示信息到UE，指示UE释放预配置资源，从而解决基站负载多大的情况：
可选的，根据所述第一指示信息确定释放所述预配置资源包括：
根据所述第一指示信息确定所述预配置资源是否有效；
若无效，则释放所述预配置资源。
在该实施中对于分配给UE之后，UE长时间不使用的预配置资源；或者是被UE占用的时间超过平均时长的预配置资源会被判定为无效的预配置资源，进一步针对无效预配置资源则可以进行释放，从而使得对于某一个UE无效的预配置资源释，及时有效的释放掉，以便基站对该预配置资源重新进行合理的分配。
可选的，所述第一指示信息包含于所述配置信息中。
可选的，所述第一指示信息用于指示所述预配置资源的有效时间或指示所述预配置资源的有效使用次数。
对于预配置资源分配给UE之后的使用情况可以通过预配置资源的使用时间以及使用的次数来确定，所以在该实施例中，可以通过设置预配置资源的有效时间以及有效次数来合理的确定预配置资源分配给UE之后是否被合理的有效的利用起来，如果没有，那么释放掉预配置资源，则可以让基站重新合理的分配预配置资源提高资源的利用率。并且基于第一指示信息指示时间或次数情况，具体实现方式可以是：
可选的，所述第一指示信息指示所述预配置资源的有效时间，则根据所述第一指示信息确定所述预配置资源是否有效包括：
确定当前预配置资源对应的时刻是否在有效时间段内；如果是，则确定所述预配置资源有效，或者如果不是，则确定所述预配置资源无效；所述有效时间段的起始时刻为预设的第一时刻，所述有效时间段的时长为所述有效时间所对应的时长值；
或者，
确定当前预配置资源对应的时刻与所述UE上一次所使用的预配置资源所对应时刻之间的时间差值，确定所述时间差值是否小于所述有效时间信息所对应的时长；如果是，则确定所述预配置资源有效，或者如果不是，则确定所述预配置资源无效。
该实施例中，UE基于时间信息来确定预配置资源是否得到了合理有效的使用，如果不是，则释放掉。从而可以保证预配置资源在分配给UE之后，能够及时的释放掉避免资源的浪费。另外，对于使用预配置资源比较频繁或者是预配置资源还在被UE使用的情况，该实施例中，则可以对预配置资源的有效时间进行延长，该实例在保证预配置资源被均衡合理使用的前提下，还能保证UE连续使用预配置资源的情况不会因为一个固定的有效时 间而打断，提高了释放无效预配置资源方案的合理性。
可选的，所述第一指示信息指示所述配置资源的有效时间，则根据所述第一指示信息确定所述预配置资源是否有效包括：
在预设的第二时刻启动定时器，所述定时器的时长为所述有效时间对应的时长值；如果确定所述预配置资源是否有效时，所述定时器正在运行，则确定所述预配置资源有效，如果所述定时器超时或停止运行，则确定所述预配置资源无效。
可选的，确定所述预配置资源有效，之后还包括
若所述UE使用所述预配置资源，则重置所述定时器。
在该实施例中，通过定时器来实现预配置资源的有效时间判定，操作方便便于实现提高了该方法的可操作性。而且对于有可能被连续使用的预配置资源，可以通过简单的重启定时器时间，来延长预配置资源的有效时间，从而达到操作简便方便实现的效果。
可选的，所述第一指示信息指示所述预配置资源的有效次数，则根据所述第一指示信息确定所述预配置资源是否有效包括：
以所述预配置资源生效之后第一次预配置资源开始计数，确定预配置资源出现的次数是否在所述有效次数内，如果是，则确定所述预配置资源有效；或者如果不是，确定所述预配置资源无效；或者
所述UE使用预配置资源开始计数，确定预配置资源出现的次数是否在所述有效次数内，如果是，则确定所述预配置资源有效；或者如果不是，确定所述预配置资源无效。
该实施例中，基于预配置资源的有效次数来判定是否有效，可以避免预配置资源的周期对分配给UE的预配置资源数量的影响，从而能有更合理的确定UE可使用的预配置资源。

具体实施方式
因为在预配置资源上发送上行数据的方法可以不用对随机接入前导码进行确定，直接进行上下行数据的传输的优点，使用预配置资源发送上行数据的方法在很多地方进行了应用，其中使用预配置资源发送上行数据的方法流程具体包括以下步骤(如图1所示)：
步骤101，基站(或服务小区)向UE发送预配置资源的配置信息；其中，该预配置资源用于所述UE空闲态时数据传输。
可选地，该配置信息可以通过RRC连接释放消息或RRC连接重配置消息或RRC早传数据完成消息发送。
可选地，基站向UE发送配置信息之后，UE进入到空闲态，并保存预配置资源的配置信息和TA。
步骤102：当UE有上行数据到达时，UE使用预配置资源和TA向基站发送Msg3，其中携带上行数据。
步骤103：基站接收到Msg3之后，若根据Msg3中携带用于指示UE没有额外数据需要发送的指示信息，则可以判断UE没有额外的数据需要传输，则将UE切换到空闲态。
但是对于NB-IoT终端或一些低移动性或静止的终端，由于其数据传输不仅具有周期性，而且移动较慢或完全静止，，UE的数据传输周期可能发生改变，此时预配置的资源无法使用，从而则会造成有大量预配置资源分配给UE之后并不能得到有效的利用或不能得到及时释放，导致资源的浪费。
为了解决上述现有技术的问题，本申请提供一种资源配置的方法，该方法可以应用于LTE或未来的通信系统，比如5G，具体可使用的场景包括图2所示的用户设备(User Equipment，UE)与演进型基站(Evolved Node B，eNB)交互的场景，其中eNB还可以是5G中的gNB。其中：
用户设备，包含手机、智能终端、多媒体设备、流媒体设备等；
eNB是LTE(4G)中UE和演进后的核心分组网演进(Evolved Packet Core，EPC)核心网之间的桥梁，eNB之间通过X2接口进行连接，主要功能有：无线资源管理、IP头压缩及用户数据流加密、UE附着时的MME选择、路由用户面数据至S-GW、寻呼消息的组织 和发送、广播消息的组织和发送、以移动性或调度为目的的测量及测量报告配置等。
为了更清楚详细的说明本申请所提供方案的具体实现过程，以下结合具体的实例对本申请实施例所提供的方法做进一步详细的说明：
如图3所示，本申请实施例提供一种资源配置方法，该方法具体可以包括以下实现步骤：
步骤301，基站(可以是eNB或者称为网络侧设备)向UE发送第一消息，所述第一消息携带预配置资源的配置信息(或称为上行资源的预配置信息)。
在本申请实施例中，第一消息可以是RRC连接重配置消息，或者是RRC连接释放消息，或者是RRC早传数据完成消息。上述三种为具体举例，当然在具体的使用环境中第一消息也可以是其他消息。
步骤302，UE接收第一消息；
步骤303，所述UE获得第一指示信息，并根据所述第一指示信息确定释放所述预配置资源。
在本申请实施例中，根据所述第一指示信息确定释放所述预配置资源的方式可以包括两种，一种是根据所述第一指示信息确定所述预配置资源是否有效，若无效，则释放所述预配置资源；或者，若有效，则使用该预配置资源发送上行数据；另外一种是第一指示信息直接指示UE对预配置资源进行释放；以下结合两种释放预配置资源的方式对本申请实施例所提供的方法做进一步详细的说明。
释放预配置资源的第一种方式：根据所述第一指示信息确定所述预配置资源是否有效，若无效，则释放所述预配置资源；或者，若有效，则使用该预配置资源发送上行数据，则本申请实施例提供的一种资源配置方法的具体可以包括(如图4所示)：
步骤401：eNB向UE发送第一消息，所述第一消息携带预配置资源的配置信息(或称为上行资源的预配置信息)。
在本申请实施例中，该配置信息中可以包含指示预配置资源是否有效的第一指示信息，具体的该第一指示信息可以用于指示所述预配置资源的有效时间或指示所述预配置资源的有效使用次数。
1，当第一指示信息指示所述预配置资源的有效时间时，在有效时间内UE可以多次使用周期性出现的预配置资源，在有效时间过后，预配置资源即被释放；另外一种可能的实现方式中，还可以，UE使用过某一预配置资源后，则以所使用的资源位置为起始时刻，等效于将判断预配置资源有效的时间向后延长有效时间的时长，在有效时长内的预配置资源则为有效，在有效时间之后，预配置资源即被释放。
2，当第一指示信息指示所述预配置资源的有效次数时，第一指示信息可以指示从预配置资源生效时开始计数，UE使用预配置资源的次数小于或等于有效次数，则预配置资源有效，否则释放预配置资源。在另外一种可能的实现方式中，还可以，以所述UE使用预配置资源时开始计数，确定预配置资源出现的次数是否小于或等于所述有效次数，如果是，则确定所述预配置资源有效；或者，如果不是，则释放预配置资源。
本申请实施例所提供的方法主要目的是将分配给UE且失效的预配置资源转入再利用的状态，所以上述实施方式中，对于失效后的预配置资源除了释放处理以外，还可以通过以下方式中的人任意一种进行处理：
去使能预配置资源、去配置预配置资源或者去激活预配置资源。
进一步为了使得UE确定基站所配置的预配置资源，本申请实施例中的配置信息还可以包括以下信息中的任意一种或多种的组合(例如配置信息中包括A1～A3三个，则可以是选择某一个信息；另外也可以是A1与A2组合；或者A1、A3组合；或者A1、A2、A3组合)：
A1，确定预配置资源的时域信息：时域信息的具体实现方式可以通过周期也可以通过具体的时间点确定基站所配置的预配置资源，具体的：
通过周期(period)确定预配置资源，其单位可以是子帧(subframe)，系统帧(system frame number，SFN)，超帧(hyper-SFN)，毫秒，秒，分，小时，天等。第一种情况：若只配置了周期，没有配置偏移值，则需要确定周期的参考时间点，即第一个周期的开始时刻，具体起始时刻可以是接收到第一消息的时刻，或为释放RRC连接的时刻。第二种情况：若配置了周期，且配置了偏移值Offset，以周期单位和偏移值单位都是子帧为例，则在满足如下公式的SFN和子帧位置为预配置资源：((SFN×10)+subframe)mod period＝Offset。
或者，
通过预配置资源的时间点确定预配置资源，具体可以是具体的某一时刻信息，例如每天的12：00：00.000，精度到毫秒。
A2，预配置资源的频域信息，例如预配置资源出现的窄带narrowband或载波carrier，以及预配置资源的PRB数。
A3，配置消息还可能包含下行控制信息(Downlink Control Information，DCI)，其具体指示预配置资源的具体物理资源块(physical resource block，PRB)位置。
DCI用于调度上行资源，此处，基站可以在连接态向UE发送DCI，并指示该DCI是用于Idle的上行数据传输，即用于指示预配置资源，从接收到该DCI开始以上述周期依次出现预配置资源，即上述周期的起始时刻可以为接收到该DCI的时刻。
步骤402：UE接收第一消息，并根据所述配置信息中的第一指示信息确定预配置资源是否有效，若有效，则可使用预配置资源进行上行数据发送，或者，若无效，则释放所述预配置资源。
就第一指示信息可以指示预配置资源的有效时间也可以指示有效次数的情况，UE基于第一指示信息确定预配置资源是否有效的方式可以是：
1、当第一指示信息指示所述预配置资源的有效时间，则根据所述第一指示信息确定所述预配置资源是否有效包括：
方式一，确定当前预配置资源对应的时刻是否在有效时间段内；如果是，则确定所述预配置资源有效，或者，如果不是，则确定所述预配置资源无效；所述有效时间段的起始时刻为预设的第一时刻，所述有效时间段的时长为所述有效时间所对应的时长值；如图5所示第一时刻可以是某一个预配置资源周期所对应的开始时刻，即预配置资源1的时刻；在图5中根据有效时间的长度，可以确定有效时间段为第一时刻和第二时刻之间的时间段，则，对应的，如果当前预配置资源对应有效时间段中的任一预配置资源(如预配置资源1～3)，则当前预配置资源有效，或者，如果不是，则无效。即当前预配置资源为图5中的预配置资源1～3，则有效，为预配置资源4则无效。
方式二，因为预配置资源被使用一次后，后面会被连续使用的可能性很大，而且如果有些业务连续使用的时间会比较长，所以为了适应这种情况，本申请实施例在确定预配置 资源的有效性时，还根据预配置资源的使用情况，对预配置资源有效时间的起始时刻进行动态的调整，从而使得整个方案所确定的有效时间能够更准确的适应UE对预配置资源的使用情况，具体实现可以是：
确定当前预配置资源对应的时刻与所述UE上一次所使用的预配置资源所对应时刻之间的时间差值，确定所述时间差值是否小于所述有效时间信息所对应的时长；如果是，则确定所述预配置资源有效，或者，如果不是，则确定所述预配置资源无效。
如图6所示，UE使用预配置资源3，其对应第三时刻，在该实施例中，有效时间从第三时刻开始向后延长有效时间对应的时长，即预配置资源4和预配置资源5为有效的预配置资源。如果预配置资源4和5没有被使用，在有效时间之后的预配置资源6无效；或者，如果预配置资源4或5被使用，对应的预配置资源的有效时间再往后延长至少一个有效时间信息所对应的时长。
方式三：另外，为了方便实现有效时间信息的判定，本申请实施例中可以通过定时器来确定预配置资源是否有效，具体实现可以是：
在预设的第二时刻启动定时器，所述定时器的时长为所述有效时间对应的时长值；如果确定所述预配置资源是否有效时，所述定时器正在运行，则确定所述预配置资源有效，如果所述定时器超时或停止运行，则确定所述预配置资源无效。
在上述方式三的基础上，如果确定所述预配置资源有效之后，若所述UE使用所述预配置资源，则还可以重启所述定时器。重启定时器之后，定时器的时长为所述有效时间对应的时长值，即将预配置资源的有效期延长一个有效时间。
2、当第一指示信息指示所述预配置资源的有效次数，则根据所述第一指示信息确定所述预配置资源是否有效包括：
以所述预配置资源生效之后第一次预配置资源开始计数，确定预配置资源出现的次数是否小于或等于所述有效次数，如果是，则确定所述预配置资源有效；或者，如果不是，则确定所述预配置资源无效；
如图7所示，如果有效次数是3次，则UE可以使用从预配置资源1开始的3次预配置资源的任意资源，在这3次预配置资源之后，预配置资源即被释放。
还可以是，以所述UE使用预配置资源时开始计数，确定预配置资源出现的次数是否在所述有效次数内，如果是，则确定所述预配置资源有效；或者，如果不是，则确定所述预配置资源无效。
如图8所示，在预配置资源1～3对应的有效次数内，预配置资源1～3有效，若预配置资源3被使用了，则后续在判断预配置资源是否有效时，以预配置资源3为起点开始计数。
进一步，因为基站在给UE分配预配置资源时，可能会为一个UE分配多套预配置资源，本申请实施例所提供的上述方法，可以在配置信息中携带一个第一指示信息，多套与配资资源共用一个第一指示信息确定预配置资源是否有效；当然，也可以在配置信息中携带多个第一指示信息，可以是每一套预配置资源都对应一个第一指示信息，从而根据每套预配置资源对应的第一指示信息来判断预配置资源是否有效。
本申请上述实施例中的方法，实现基站到UE的预配置资源和使用的控制，使UE能够在一定条件满足时释放预配置资源，以避免预配置资源长期不使用所造成的浪费问题。
释放预配置资源的第二种方式：如果预配置资源配置给UE后不能合理利用，则会导致资源的浪费。在网络侧出现负载过重的问题时，如果不能做到及时释放预配置资源，则 会造成网络连接中断等问题。为此，本申请实施例所提供的方法中，在基站负载过大时，基站可以直接发送第一指示信息指示UE对预配置资源进行释放，从而解决预配置资源的浪费以及网络中断问题。该实施例的具体实现方式可以是(如图9所示)：
步骤901：eNB向UE发送预配置资源的配置信息。
步骤902：eNB向UE发送释放预配置资源的第一指示信息；
该第一指示信息还可以称为去使能指示、去激活指示、去配置指示，用于通知UE不能再使用预配置资源发送上行数据。
具体的，发送第一指示信息的方式可以是：
1、eNB向所述UE发送P-RNTI加扰的PDCCH，所述PDCCH或所述PDCCH调度的paging消息携带所述第一指示信息，或者，所述PDCCH携带的直接指示携带所述第一指示信息。或者，2、eNB向所述UE发送唤醒信号WUS，所述WUS携带所述第一指示消息。
所述PDCCH可以是MPDCCH(MTC PDCCH)或NPDCCH(Narrowband PDCCH)。
以下结合具体的举例，对eNB使用paging消息或直接指示携带所述第一指示信息的实现方式做进一步说明，包括：
B1，当使用PDCCH调度的paging消息或直接指示携带所述第一指示信息时，其具体实现方式可以是：
P-RNTI加扰的PDCCH中包含DCI format 6-2或DCI format N2，其可用于发送paging消息或直接指示(direct indication)，其中有一个比特flag，用于指示该DCI format 6-2或DCI format N2发送的是paging消息还是直接指示。
当flag＝0时，DCI format 6-2或DCI format N2用于发送direct indication，DCI format 6-2发送该direct indication的内容如表1所示，其共包含8个bits，1-5比特已经被使用，可以使用6-8中任一比特来携带第一指示信息。
表1直接指示(direct indication information)
Bit direct indication information
1 systemInfoModification
2 etws-Indication
3 cmas-Indication
4 eab-ParamModification
5 systemInfoModification-eDRX
6,7,8 未使用
DCI format N2发送该direct indication的内容如表2所示，其共包含8个bits，1-2比特已经被使用，可以使用3-8中任一比特来携带第一指示信息。
表2直接指示(direct indication information)
Bit direct indication information
1 systemInfoModification
2 systemInfoModification-eDRX
3,4,5,6,7,8 未使用
当flag＝1时，DCI format 6-2或DCI format N2用于调度Paging消息，可以在Paging消息中携带第一指示信息。另外，Paging消息中包含UE ID即S-TMSI，用于指示具体哪 个UE被寻呼，所以在该申请实施例中，可以对需要释放的预配置资源进行选择性的释放，即根据第一指示信息是否与UE ID关联，来确定需要释放的预配置资源是哪一个或者是那几个，具体实现可以是：
方式一：若所述第一指示信息与所述paging消息中的UE ID不关联，接收到第一指示信息的UE都释放预配置资源；
方式二：若所述第一指示信息与所述paging消息中的UE ID关联，所述接收到第一指示信息的UE确定自身的UE ID是否与所述paging消息中的UE ID相同，如果是，则释放预配置资源。
当然，在该实施例中除了第一指示信息可以与UE关联以外，还可以与一个UE的一套或者多套预配置资源对应，eNB可以指示具体释放那一套预配置资源。例如，当使用direct indication来指示释放时，可以使用预留的6-8比特中的部分比特或全部比特来对应指示多套预配置资源的中一套或者是多套预配置资源释放，例如使用2个比特，至少可以指示2套预配置资源释放，使用3个比特，可以指示3套预配置资源释放。当使用Paging消息来指示释放时，对比特数没有限制。可以任意指示需要释放的预配置资源。
B2，eNB向所述UE发送唤醒信号(Wake Up Signal，WUS)，所述WUS携带所述第一指示消息。具体的，可以使用新的WUS信号序列作为第一指示信息来指示释放预配置资源。
在该实施例中，WUS用于指示eNB是否发送P-RNTI加扰的PDCCH，若WUS指示发送，则UE检测P-RNTI加扰的PDCCH来检测DCI format 6-2，若WUS指示未发送，则UE不检测，以节省UE功耗。
步骤903：UE接收eNB发送的第一指示信息，并根据该第一指示信息释放预配置资源。
在该实施例中，如果采用唤醒信号携带第一指示信息，而且eNB使用新的WUS信号序列作为第一指示信息，则UE根据该第一指示信息释放预配置资源包括：
UE接收WUS后，若所述WUS的信号序列与预设信号序列相同，确定所述WUS携带所述第一指示信息，则释放所述预配置资源。
在本申请实施例中，eNB可以在负载过大的情况下直接通过direct indication或Paging消息来指示UE释放预配置资源，从而快速有效的降低eNB的负载。
针对UE变换小区的场景，在UE的小区变换后其对应的预配置资源则不能再使用，如果再不进行释放则会导致资源的浪费，针对这个问题本申请还提供另外一种资源配置方法，具体包括(如图10所示)：
步骤1001：源网络侧设备(或称为源小区)向UE发送第一消息，所述第一消息携带预配置资源的配置信息。
步骤1002：当所述UE确定服务小区发生改变时、或者当所述UE发生小区重选时，UE向目标网络侧设备(或称为目标小区)发送第二消息，第二消息包含第一指示和标识；该第一指示用于指示UE配置有预配置资源。所述第二消息可以是以下消息中的任一种：
RRC连接建立请求(RRC Connection Request)消息
RRC连接恢复请求(RRC Connection Resume Request)消息
RRC早传数据请求(RRC Early Data Request)消息
RRC连接设置完成(RRC Connection Setup Complete)消息
UE辅助信息(UE Assistance Information)消息
UE信息响应(UE Information Response)消息
其中，携带的标识为UE服务小区发生改变前或者小区重选前对应的源小区标识或源网络侧设备的标识，如物理小区标识(Physical Cell Identity，PCI)，全球小区标识ECGI或eNB ID等。
步骤1003：目标网络侧设备在接收到第一指示和标识后，向源网络侧设备发送第三消息，所述第三消息中可以携带第二指示，第二指示用于指示源网络侧设备释放UE对应的预配置资源，其中第二指示信息可以包含以下一种：
用于指示终端在目标小区接入；
用于指示终端移动到目标小区；
用于指示释放终端的预配置资源；
此外，第三消息还包含终端的标识，如C-RNTI或S-TMSI或Resume ID。
步骤1004：源网络侧设备向目标小区发送响应消息，所述响应消息中携带第三消息的确认指示，指示源网络侧设备成功接收到第三消息；可选地，还包含所述终端的业务模式信息，所述业务模式信息包含所述终端特定业务的发起周期、数据量信息等。
步骤1005：目标网络侧设备向所述终端发送预配置资源的配置信息，给终端分配预配置资源。
在本申请实施例中，当UE移动到另一个小区并接入时，指示给目标小区该UE配置有预配置资源，使得目标小区指示源小区释放预配置资源。从而保证预配置资源能够在UE进行小区变换后及时释放。
如图11所示，基于实施例一至三提供的方法，本申请实施例所提供的一种终端设备，包括：
该终端设备1100可包括：处理器1102、收发器(可以是发射器1104、接收器1106集成在一起的完整模块，也可以是发射器1104、接收器1106分别独立实现发射功能和接收功能)、耦合器1108和存储器1110。在本申请的一些实施例中，这些部件可通过总线或者其它方式连接，其中，图11中以通过总线连接为例。
耦合器1108用于将通信号分成多路，分配给多个的接收器1106。
